Yep, ports in an "up" state, but LACP not working is the sign of bad
cabling: had been hit by this overnight once when I was preparing to
leave the facilities next day for conference, but ought to make 10G
for the new servers working. Took around 1/2 hour to sense what
happened at that time (tx was going to, say, port A and rx -- to port
B, but overall all ports were receiving tx and rx) and 3 hours for
rewiring and swearing: probably I am more skilled in the former than
in the latter ;)
Thought that you had checked this in the first place; my bad.
Thanks for sharing!
